In particular, the possibility to share large amounts of memory by many worker threads has lead to a boost in the adoption of non-blocking coordination algorithms, which have been proven to offer higher scalability when compared to their blocking counterparts based on critical sections. In this article we present an innovative non-blocking algorithm for computing Global Virtual Time (GVT) — namely, the current commit horizon-in multi-thread PDES engines to be run on top of multi-core machines. Beyond being non-blocking, our proposal has the advantage of providing a logarithmic (rather than linear) number of per-thread memory operations — read/write operations of values involved in the reduction for computing the GVT value-vs the amount of threads participating in the GVT computation. This allows for keeping low the actual CPU time that is required for determining the new GVT value. We compare our algorithm with a literature solution, still based on the non-blocking approach, but entailing a linear number of memory operations, quantifying the advantages from our proposal especially for very large numbers of threads participating in the GVT computation.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122251261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for the different organization involved in the Space domain (e.g. NASA, ESA, Roscosmos, and JAXA) and their industrial partners, it is difficult to implement HLA simulators (called Federates) able to interact and interoperate in the context of a distributed HLA simulation (called Federation). The lack of a common FOM (Federation Object Model) for the Space domain is one of the main reasons that precludes a-priori interoperability between heterogeneous federates. To fill this lack a Product Development Group (PDG) has been recently activated in the Simulation Interoperability Standards Organization (SISO) with the aim to provide a Space Reference FOM (SRFOM) for international collaboration on Space systems simulations. Members of the PDG come from several countries and contribute experiences from projects within NASA, ESA and other organizations. Participants represent government, academia and industry. The paper presents an overview of the ongoing Space Reference FOM standardization initiative by focusing on the solution provided for managing the execution of an SRFOM-based Federation.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132324193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The balance between traffic modeling details and performance has made Mesoscopic Traffic Simulation one of the key solutions for traffic controllers and policy makers. Mesoscopic traffic simulators offer acceptable speed in simulating normal traffic. However, when traffic prediction and optimization for large scale networks come into context, the performance of mesoscopic traffic simulators is unsatisfactory in optimizing a massive number of control parameters for a much longer prediction horizon. This issue again emphasizes the need to further speed up mesoscopic traffic simulation. This paper proposes a comprehensive framework to massively speed up mesoscopic traffic simulation using GPU without compromising its correctness and realistic modeling property. It also gives an in-depth analysis into the trade-off between simulation correctness and performance speedup. By combining the power of GPU with optimal design and data structures, mesoscopic traffic simulation is able to speed up to more than 6 times compared to original CPU implementation.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125390644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, one rising PDES paradigm — referred to as share-everything PDES — is no longer based on the concept of (temporary) biding of simulation objects to worker threads. Rather, each worker threads can — at any time — pick from a fully shared event pool an event to process which can be destined to whatever simulation object. While attention has been posed on the design of concurrent shared pools, allowing non-blocking parallel operations, the scenario where two (or more) threads pick events destined to the same simulation object still lacks adequate synchronization support. In fact, these events are currently sequentialized and processed in a critical section touching the simulation object state, thus leading threads to mutually block each other. In this article we present the design of a share-everything speculative PDES engine that prevents mutual thread blocks because of the access to a same object state. In our design, the non-blocking property is seen as a vertical attribute of the engine (not only of the event pool). This vertical view demands for innovative event-dispatching schemes and, at the same time, innovative interactions with (and management of) the fully-shared event pool, which are features that we embed in our innovative design.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133532837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growth of urban environments, as well as the use of ICT in enabling applications and services, has encouraged several works on the modeling of transportation. High mobility of vehicles in such a context consists of a significant challenge in modeling traffic. Several microscopic and macroscopic models have been designed aiming to represent the movement of vehicles accurately in road segments, involving different levels of complexity, precision, and realism. Out of these models, Free-flow models have shown useful due to being light and reasonably accurate for estimating load in short-time predictions. A recent free-flow traffic flow modeled using queues assumed constant vehicle speed along the road segment; this assumption may lead to a lack of realism and accuracy. Therefore, we propose a free-flow model based on this previous work where the road segment is split into several intervals, representing the oscillations of the speed of vehicles. The proposed model has shown correctness comparable to the previous free-flow model, considering that it has included speed varying behavior of vehicles.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"428 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125963917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Those techniques are used in cases of absent end-to-end connection such as in Delay Tolerant or Opportunistic Networks. The study of message transmission processes and contact information in such networks has gained more attention nowadays, where contact information and message transfer have a great impact on Store-Carry-Forward routing decisions. The performance of routing mechanisms is measured based on bandwidth utilization and energy consumption regarding the delivery ratio. Therefore, in this paper we present a study framework to formulate the message propagation process in addition to contact information with a view on energy consumption. The study gives a detailed expression of contact information such as contact probability based on node density and transmission range in a bounded area. Furthermore, the message exchange process as element of channel utilization and energy consumption will be studied. Based on our simulation experiment results we evaluate the influence of various parameters on each other and finally on the system performance.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123646989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
